生物活性

製品説明	Benpyrine racemate ((Rac)-Benpyrine) is a potent, highly specific and orally active inhibitor of TNF-α and attenuates TNF-α-induced inflammation, thereby reducing liver and lung injury.
in vitro	Benpyrine directly binds to TNF-α and blocks TNF-α-trigged signaling activation.^[1]
in vivo	Benpyrine attenuates TNF-α-induced inflammation in endotoxemic murine model, thereby reducing liver and lung injury, and significantly reliefs the symptoms of collagen-induced arthritis and imiquimod-induced psoriasiform inflammation in mice.^[1]

細胞アッセイ	細胞株	RAW264.7 macrophages
	濃度	5, 10 or 20 μM
	反応時間	12 h
	実験の流れ	RAW 264.7 cells were grown to 50−70% confluence in a glass chamber, pretreated with DMSO or benpyrine for 12 h, and then stimulated with 10 ng/mL TNF-α for 2 h. Cell treatments were terminated by washing the cells with PBS, followed by fixation with freshly prepared 4% paraformaldehyde in PBS for 20 min. The fixed cells were washed three times with PBS and then permeabilized with 0.25% Triton X-100 in PBS for 10 min. After blocking with 2 mg/mL BSA for 1 h at room temperature, we added the NF-κB/p65 antibody at a 1:1000 dilution at 4 °C overnight, washed three times with PBS, then incubated with a 1:500 dilution of the secondary antibody for 1 h at room temperature in the dark. Finally, 4′,6-diamidino-2-phenyl indole (DAPI) was used to stain the nuclei at 37 °C for 30 min in the dark.
